Phys.org / 5 reasons the COP30 climate conference failed to deliver on its 'people's summit' promise

As the sun set on the Amazon, the promise of a "people's Cop" faded with it. The latest UN climate summit—known as Cop30, hosted in the Brazilian city of Belém—came with the usual geopolitics and the added excitement ...

Phys.org / Mystery of how turtles read their magnetic map solved—they feel the magnetism

Loggerhead turtles are able to sense Earth's magnetic field in two ways, but it wasn't clear which sense the animals use to detect the magnetic field when navigating using the magnetic map they are born with. Now researchers ...

Phys.org / Belief in divine intervention shapes consumer reactions to corporate crimes and punishments

A company dumps toxic chemicals into a river to save money. Around the same time, a major storm strikes and causes damage to that same company. Is it just a coincidence? According to new research from Andrew Gershoff, professor ...
